I wrote a css style for FR that is dark grey and light grey but the links to external webpages are now dark blue and there is a thick red outline to the search box when active.
Did you just delete the bookmarks? I can’t think of anything that bookmarklets would do that would cause that issue.
I am curious about the css you wrote. What does it do and how is it used?
Also, have you closed and reopened your browser?
thanks,
